What is a filegroup?
Filegroups. The filegroup contains the primary data file and any secondary files that aren't put into other filegroups. User-defined filegroups can be created to group data files together for administrative, data allocation, and placement purposes.
How do filegroups work?
Filegroups use a proportional fill strategy across all the files within each filegroup. As data is written to the filegroup, the SQL Server Database Engine writes an amount proportional to the free space in the file to each file within the filegroup, instead of writing all the data to the first file until full. It then writes to the next file. For example, if file f1 has 100 MB free and file f2 has 200 MB free, one extent is given from file f1, two extents from file f2, and so on. In this way, both files become full at about the same time, and simple striping is achieved.
What are the two operating systems in SQL Server?

Should SQL Server use compression?
For space savings, it is highly recommended to use data compression instead of file system compression. When multiple instances of SQL Server are running on a single computer, each instance receives a different default directory to hold the files for the databases created in the instance.
Can a database have multiple files?
Most databases will work well with a single data file and a single transaction log file. If you use multiple data files, create a second filegroup for the additional file and make that filegroup the default filegroup. In this way, the primary file will contain only system tables and objects.
Can a file be used by more than one database?

Can data files be compressed?
Data files should not be put on compressed file systems unless the files are read-only secondary files, or if the database is read-only. Log files should never be put on compressed file systems. If the file is on a raw partition, os_file_name must specify only the drive letter of an existing raw partition.
